Onthe eater end of this shaft 101 is a. pinion 10.3 niesl'iing with alarge gear 10G', which is rigidly connected during operation (thoughadi? ably as hereiiiat'ter described) to the shaft .30. rrordingfly,Whenever the printing press is rotated, the shaft is rotated at aroi-res;ondig speed. 1t is to be linden stood that the diameter of thefading rollers 51 is; the pitch diameter of the gear 106, so that, thefeeding action of 'these rollers is that of the printing mechanism. orother nnrhanisni, which receives the paper.

Thewiping fingers and feed rollers and their shafts may be mounted insmall` compass beneath the 'forward ends of a pile of pa.- per, and arethus outof the way.
